1295 depiction of Alice arriving at Acre

Alice of Champagne (c. 1193 – 1246) was the eldest daughter of Queen Isabella I of Jerusalem and Count Henry II of Champagne. In 1210, Alice married her stepbrother King Hugh I of Cyprus, receiving the County of Jaffa as dowry. After her husband's death in 1218, she assumed the regency for their infant son, King Henry I. Her attempts to bolster her claim to Champagne and Brie in France failed. Due to a debate with her uncle Philip of Ibelin, she left Cyprus in 1223. In exile, she married Bohemond, the heir apparent to the Principality of Antioch and the County of Tripoli, but their marriage was annulled. In 1229, she unsuccessfully laid claim to the Kingdom of Jerusalem against the absent Conrad II. In 1240, she married Raoul of Nesle and the High Court of Jerusalem proclaimed them regents for Conrad in 1243, although their power was nominal. Raoul left the kingdom, and Alice, before the end of the year. Alice retained the regency until her death in 1246. (Full article...)

Existential quantifier, used in logic to express existence

Existence is the state of having being or reality. It is often contrasted with essence, since one can understand the essential features of something without knowing whether it exists. Ontology studies existence and differentiates between singular existence of individual entities and general existence of concepts or universals. Entities present in space and time have concrete existence, in contrast to abstract entities, like numbers and sets. Other distinctions are between possible, contingent, and necessary existence and between physical and mental existence. Some philosophers talk of degrees of existence but the more common view is that an entity either exists or not, with no intermediary states. It is controversial whether existence can be understood as a property of individual objects and, if so, whether there are nonexistent objects. The concept of existence has a long history and played a role in the ancient period in pre-Socratic, Hindu, Buddhist, and Daoist philosophy. (Full article...)

Original premises of Blackrocks

Blackrocks Brewery is a craft brewery in Marquette, Michigan. Taking the name from a local landmark, former pharmaceutical salesmen David Manson and Andy Langlois opened Blackrocks in 2010. They originally brewed their products in the basement of a Victorian-style house (pictured), and the building's two other floors were used as a taproom. By 2013, persistent high demand for Blackrocks' beer led Manson and Langlois to expand their brewing capacity, including the purchase and conversion of a former Coca-Cola bottling plant. In the early 2020s, they expanded Blackrocks' taproom into an adjacent property, which doubled its available indoor area. Blackrocks produced 12,687 barrels of beer in 2023, up about 11 percent from the year prior, and they are the largest craft brewery in Michigan's Upper Peninsula. Their most popular beer is 51K, an American IPA named for a local ski marathon. (Full article...)
